Applications
The MBB02070C3300FCT00 is a precision metal film resistor suited for audio amplifier feedback networks, instrumentation front-end voltage dividers, and active filter designs where 1% resistance accuracy and low thermal noise are required. Its 350 V AC rating allows direct deployment in mains-referenced measurement circuits, line snubbers, and current-sense networks in switching power supplies. The axial through-hole format with 28 mm leads enables use in prototype boards, industrial control PCBs, and high-reliability power metering equipment where SMD mounting is not practical.

Frequently Asked Questions
What resistance value, tolerance, and power rating does the MBB02070C3300FCT00 carry for precision circuit use?
The MBB02070C3300FCT00 is a 33 Ω resistor with 1% tolerance and a 0.6 W power rating. The tight 1% tolerance ensures accurate voltage division ratios in instrumentation circuits, while the 0.6 W rating allows operation in signal conditioning networks where modest continuous dissipation occurs without requiring oversized heat-spreading designs.
How does the 350 V AC rating of the MBB02070C3300FCT00 expand its usability in power electronics designs?
The 350 V AC rating allows the MBB02070C3300FCT00 to be used directly in mains-referenced circuitry such as RCD snubbers, EMI filter bleed resistors, and high-voltage measurement dividers without risk of dielectric breakdown. Standard film resistors rated below 200 V cannot be used in these positions, so the elevated 350 V rating makes this part a direct fit for power metering ICs and line-interactive UPS circuits.
Why is a metal film construction preferred over carbon film for the MBB02070C3300FCT00 in audio and instrumentation applications?
Metal film resistors like the MBB02070C3300FCT00 exhibit significantly lower current noise (typically below -20 dB relative to carbon film) and better temperature coefficient stability, often below 100 ppm/°C. In audio preamplifier gain networks or precision ADC input dividers, this lower noise floor prevents the resistor itself from degrading signal-to-noise ratio, which carbon film resistors at the same 33 Ω value would risk doing in high-gain stages.
What physical dimensions should a PCB designer account for when placing the MBB02070C3300FCT00 in a through-hole layout?
The MBB02070C3300FCT00 has a 2.5 mm body diameter and 28 mm lead length in an axial tubular form factor. PCB designers should plan for a minimum lead pitch of 7.5 mm to 12.5 mm (bent to standard 2.54 mm grid) depending on the mounting orientation, leaving sufficient board clearance above the 2.5 mm body for the rated 350 V AC creepage distances in dense power supply layouts.
